SPECIFICATION forming part of Letters Patent No. 410,765, dated September 10, 1889.l

Application filed March 15, 1889. Serial No. 803,411. (No model.)

ters of reference marked thereon,whi0h form` a part of this specification.

. My invention relates to a novel construction of glue-heaters, wherein the heat applied to the pot of glue is obtained from an adjacent boiler or steam-generator.`

My invention is vdesigned as anA improvement upon the devices heretofore in use, in which a water-jacket surrounds the glue-pot and a steam-heatin g chamber is inserted With-V in said water-jacket to obtain the desired result. It has been customary, in this form of heater, to construct the steam-heating chamber in part or wholly integral with the waterjacket. This construction is necessarily expensive and objectionable, for the reason that should the steam-heating chamber become Worthless by rusting ont or by freezing and bursting it becomes necessary to supply an entirely new` apparatus.

The invention consists in the details of construct-ion and combinations of parts hereinafter fully described and claimed.

The accompanying drawing contains aside view of my invention with certain parts in Vertical section.

A indicates a pipe leading from a source of steam-supply and entering the horizontal end of a pipe-elbow A.

A2 indicates a foot, preferably secured to the floor, work-bench, or other suitable horizontal support adjacent to the place at which it is desired to employ the glue-heater. A supporting pipe or bar A3 lits into said post and enters a screw-threaded tubular eXtension d on the lower end of said elbow at its upper end, and thus supports the glue-heater.

B indicates a short pipe leading from the upper end of the coupling A and externally screw-threaded on its upper end.

C indicates a cylindrical casing or opentopped receptacle forming an outside waterjacket. An opening formed in the bottom of said casing is provided with a rim c, internally screw-threaded and adapted 'to lit the upper end of the pipe B. C represents a stopcock inserted in the bottom of said casing to permit the Water to be drawn therefrom,when desired. B indicates a hollow steam cap or head attached to the upper end of said pipe i B within the casing C. The said steam-cap B consists of an internally-screw-threaded 6o rim b, upwardly inclined, and vertical sides and a dat top. b2 is a square depression or one of other than circular form, formed in the top of said cap and adapted to receive a square or other suitable tool, by which the head may be unscrewed and removed.

b3 indicates integral posts or studs located inside the head and adapted to strengthen the same.

B2 indicates a stop-cock inserted in the 7o pipe B torpermit the escape of air and water therefrom at the time of turning on the steam.

I have found that in use it is often necessary to remove the glue-pot from the heater to have it in readiness near the place Where the work is performed. This is objectionable, as the glue will in a short time cool off and harden. To obviate this difficulty,I have devised the following means, which consist of a glue-pot D, provided near its upper end 8o with an annular iange d. E indicates a cylindrical casing or open-topped receptacle capable of insertion into the casing C and forming an inside Water-jacket. E is an outwardlyturned flange formed on the upper edge of the 8 5 casingE and adapted to rest upon the top of the casing C. The glue-pot D is placed within the casing E. e indicates ears formed upon the iiange E', and e abail attached at each end to said ears,by which the inside water-jacket 9o and glue-pot may be removed, as desired. It will be seen that a second Water-jacket is afforded, which will retain its heat for some time after bein g removed from the heater, and thus preserve the desired consistency of the glue.

The parts of my invention being constructed as described, the operation is as follows: A sufficient quantity of Water having been poured into the casing C, and the glue- Ico pot being suitably filled, the casing E is placed in position,in which water is also poured, and

the glue-pot placed therein. The stop-coek B2 is then opened and steam admitted from the source of supply through the pipesAand B to the cap B', which gives ont the desired heet. Any vproducts of condensation will readily pass off through the pipes A and B. Should it be desirable to gain access to the inner part of the cap or pipes, it is an easy matter to unscrew the cap by inserting :t suitable tool in the depression b2 and turningthe same. Vhen the device is not in use, the witter in the easing can be easily removed by means of the stop-cock C.

I claim as my invention-` l. A glue-heater comprising a steam-supply pipe, nVWater-jaeketnd :t steam-cap removably secured upon seid pipe within the waterjncket, substantially as set forth.

2. A glue-heater comprising a Water-jacket, :t steam-supply pipe extending into the same, and :i stenmeap removablysecured upon said pipe, substantially as set forth.

3. A glue-heater comprising a water-jacket, n steam-supply pipe extending into the same, and esteem-cap connected by n screw-joint with the pipe and provided in its top with n depression of `other than circular forni, substantially :is set forth.

4. A glue-heater comprising :L waterjncket, :t steam-supply pipe extending` into the sinne, and n stezun-eap secured upon said pipe, seid steam-cap provided internally with integral posts or studs, substantially ns set forth.

5. A glue-heater comln'isingl an outside WzL- ter-jacket, an inside Wnterqjzicket, a glue-pot, and a heater, substantially as set forth.

G. A glue-heater comprising an outside water-jacket, n steam-pipe extending into said outside Water-jacket, :t glue-pot having a flange near its upper edge, and an inside vmter-jacket resting upon the upper edge of the outside Water-jacket and supporting the gluepot by engagement with the flange thereof, substantially as set forth.

7 A glue-henter comprising n Water-jacket, e steam-cap, and a steam-supply pipe secured to said steam-cap, combined with a pipe-elbow,a pipe leading from the source of steamsnpply, and the said steam-supply entering ssi-id elbow, said pipe-elbow lm'ving a tubular extension, :t supporting-pipe or bnr, the upper end of 'which enters said tubular extension, and the lower end of which rests on nn adjw cent supporting-surfaee, substantially ns set forth.

In testimony that I claim the .foregoing :is my invention I niix my signature in presence of two witnesses.
